Tag Archives: SFP-10G-SR

The SFP-10G-SR is a Cisco multimode 10G transceiver. It supports up to 400m link length when uses 4700Mhz KM OM4 multimode fiber (MMF ). Usually, it was used in a switch SFP slot and support on a wide range of Cisco switches and routers. In the market, the SFP-10G-SR price is various, from $ 10 to $ 800. Which one should I choose? Knowledge of SFP-10G-SR price and compatibility will be provided in this blog.

Details about Cisco SFP-10G-SR
The SFP-10G-SR is a Cisco 10G SFP+ transceiver module. It supports bi-directional, serial-optical data transfers across fiber optic networks. It is equipped with two connectors: a SFP+ male edge connector that plugs into the switch’s SFP+ port, and a duplex LC female connector for the fiber optic patch cable. Since it is hot-pluggable compliant, the Cisco SFP-10G-SR transceiver can be plugged directly into any Cisco SFP+ based transceiver port, without the need to power down the host network system. This capability makes moves, adds, and changes quick and painless.

Knowledge of SFP-10G-SR Compatibility
When you buy SFP-10G-SR transceivers for your switch, you are told to buy “brand” SFP-10G-SR from your network equipment manufacturer in order to keep your system running properly and safely. The “brand” SFP-10G-SR compatibility may never have any issues and the price is therefore very high, usually several hundred dollars. But since the transceivers are all manufactured based on MSA (Multi-source Agreement), which strictly define the operating characteristics of optical transceivers so that system vendors may implement ports in their devices that allow MSA compliant transceivers produced by name brand, as well a third party vendors, to function properly. Transceivers that manufactured by third party vendors usually called compatible transceivers, such as Cisco compatible SFP-10G-SR transceivers. Usually, these compatible transceivers are tested on the corresponding switch before selling, therefore, the compatibility can also be ensured. Cisco SFP-10G-SR matrix can be found here.

SFP-10G-SR Price Comparison
Since equipment SFP-10G-SR vendors all rely on MSAs when designing their transceivers, every supplier can produce the transceiver modules with the same functions. For this reason, there are many module suppliers from which customers can choose freely. As we all know, freedom of choice is the foundation of the efficient operation of markets. In order to gain a bigger share of the market, those vendors may act as efficiently as possible, which may drive down costs and offer cheaper transceivers to customers. Following table gives a SFP-10G-SR price comparison based on several popular transceivers vendors for your reference.

The Cisco 4500 series switches provide high performance, mobile, and secure user experiences through Layer 2-4 switching investments. Since they have a centralized forwarding architecture that enables collaboration, virtualization, and operational manageability through simplified operations, therefore, more and more people choose to use 4500 series switches in their network. As we know, once we use a switch, we may use some transceiver modules. In this article, some SFP+ transceivers that supported for Cisco 4500 series switches will be introduced.

Cisco 4500 Series Switch Overview
Cisco 4500 series switches include 4500 Series and 4500E Series switches. Among, 4500 series include Catalyst 4503 Switch, Catalyst 4506 Switch, Catalyst 4507R Switch, Catalyst 4510R Switch. With forward and backward compatibility spanning multiple generations, the new Cisco Catalyst 4500E Series provides exceptional investment protection and deployment flexibility to meet the evolving needs of organizations of all sizes, which include Catalyst 4503-E Switch, Catalyst 4506-E Switch, Catalyst 4507R+E Switch and Catalyst 4510R+E Switch. SFP+ ports operate in full-duplex mode and are present on the WS-X4516-10GE and WS-X4013+10GE supervisors, as well as some line cards. These ports use the 10GBASE-SR, 10GBASE-LRM and 10GBASE-LR SFP+. SFP+ connectors vary with interface type and may use multimode fiber (MMF) or single-mode fiber (SMF) cable.

Supervisor Engine for Cisco 4500 Series Switch
The Cisco supervisor engine is the brain of many of Cisco’s switches, which refers to specific modules that can be placed in a modular chassis. Cisco 4500 series and 6500 series switches both require supervisor engines to work. In fact, the transceivers type depends on the port type of supervisor engine. So, it’s necessary to identify the port type of your supervisor engines first. In following table, I display some supervisor engines that both supported for Catalys 4500 Series Switches and SFP+ transceivers. Please note that WS-X4516-10GE, WS-X4013+10GE, WS-X45-Sup6-E, WS-X45-Sup6L-E and WS-X4606-X2-E can also be used for X2 transceivers with CVR-X2-SFP10G converter.

SFP+ Transceivers for Cisco 4500 Series Switch
According to Cisco 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix, all supervisor engines mentioned above can support SFP-10G-SR, SFP-10G-LRM, SFP-10G-LR, SFP-10G-SR-S and SFP-10G-LR-S SFP+ transceivers. Besides, WS-X4712-SFP+E, WS-X45-SUP7-E, WS-X45-SUP7L-E, WS-X45-SUP8-E and WS-X45-SUP8L-E can also support SFP-10G-ER, SFP-10G-ZR, SFP-10G-ER-S and SFP-10G-ZR-S SFP+ transceivers. All SFP+ transceievrs can be found in FS.COM.

There are many kinds of 10G optical transceivers in the market such as SFP+, XFP, X2 and XENPAK. So when we use these modules, the most confusing problem is if we can interconnect SFP+, XFP, X2 and XENPAK. Besides this, some module users also want to know if they can connect SFP to SFP+ or if then can connect 10GBASE-SR modules to 10GBASE-LR modules. In this article, I will display some common questions often asked by module users and give the right answer mainly based on Cisco optical transceivers.

1. Can we interconnect SFP-10G-SR to XENPAK-10GB-SR or X2-10GB-SR?
The answer is yes. For this problem, you just need the correct optic on each side. If your optics are singlemode you need singlemode patch cord. If your optics are multi-mode then you need multi-mode patch cord. SFP-10G-SR, XENPAK-10GB-SR and X2-10GB-SR are all multi-mode optics, so a multi-mode fiber can solve this problem.

2. Can LC-SC patch cord connect X2-10GB-SR between SFP-10G-SR?
Yes, it’ll work fine as long as your fiber patch cord is multi-mode. Actually, the SFP+ requires LC connector but the X2 may require a SC connector. So when connect SFP-10G-SR to X2-10GB-SR, we must use a LC-SC patch cable (LC connector on one fiber end, SC connector on the other fiber end).

3. Is it possible to connect X2-10GB-LR to SFP-10G-SR?
The answer is not possible. The Cisco X2-10GB-LR module supports a link length of 10 kilometers on standard single-mode fiber (SMF, G.652). However, the Cisco SFP-10G-SR module supports a link length of 300m on OM3 multi-mode fiber (MMF,OM3) and 400m on OM4 multi-mode fiber (MMF,OM4). Actually, you need to use modules with the same wavelengths, i. e. SR to SR or LR to LR.

4. Can we connect SFP-10G-SR to GLC-SX-MM?
The SFP-10G-SR is 10 Gbps only. The GLC-SX-MM is 1 Gbps only. This question means can we force SFP-10G-SR to use 1Gbps speed? This is a very common question and the response will always be the same. The answer is NO. Because the SFP-10G-SR is 10 Gbps only. It runs at 10 Gbps link rate and no other speed. GBIC, SFP, X2, QSFP, CFP modules will only negotiate to one speed and one speed only. You cannot interconnect them.

5. Can we connect GLC-SX-MM to GLC-LH-SM?
Some users wonder if they can use GLC-SX-MM together with GLC-LH-SM? In fact, the GLC-SX-MM is multi-mode LED-based. The GLC-LH-SM is singlemode laser-based. They may (sometimes) work with mode conditioning patch (MCP) cables but it’s not generally a good idea unless it’s completely unavoidable.

As bandwidth demands increase, fiber optic patch cables and fiber optic transceivers become more and more important in fiber optic data transmission, especially in data transmission between the switches and equipment. But with so many different kinds of patch cables available in the market, which one is suitable for may optical transceiers? This article may on this issue to provide some solutions. Before starting this topic, it is necessary for us to review the basic knowledge of the fiber optic transceiver and fiber optic patch cable.

Fiber Optic Transceiver Overview
Fiber Optic Transceiver is a self-contained component that can both transmit and receive. Usually, it is inserted in devices such as switches, routers or network interface cards which provide one or more transceiver module slot. There are many optical transceivers types, such as SFP+ transceiver, X2 transceiver, XENPAK transceiver, XFP transceiver, SFP (Mini GBIC) transceiver, GBIC transceiver and so on.

Fiber Optic Patch Cable Overview
Fiber optic patch cable, also known as fiber jumper or fiber optic patch cord. It is composed of a fiber optic cable terminated with different connectors on the ends. Fiber optic patch cables are used in two major application areas: computer work station to outlet and patch panels or optical cross connect distribution center. According to fiber cable mode, cable structure or connector types etc., fiber patch cable can be divided into different types.

1.Single-mode and Multimode Patch Cable
According cable mode, patch cables can be divided into single-mode and multimode fiber patch cable. The word mode means the transmitting mode of the fiber optic light in the fiber optic cable core. Single-mode patch cables are with 9/125 fiber glass and are yellow jacket color, while multimode patch cables are with OM1 62.5/125 or OM2 50/125 fiber glass and are orange color. In addition, there is 10G OM3 and OM4 multimode patch cables which cable jacket are usually aqua.

2.Simplex and Duplex Patch Cable
Simplex fiber patch cable is consist of single fiber core, while duplex fiber patch cable is consist of two fiber cores and can be either singlemode or multimode. Additionally, there is also ribbon fan-out cable assembly (ie. one end is ribbon fiber with multi fibers and one ribbon fiber connector such as MTP connector (12 fibers), the other end is multi simplex fiber cables with connectors such as ST, SC, LC, etc.).

3.LC, SC, ST, FC, MT-RJ, E2000, MU and MPO/MTP Patch Cable
Fiber optic patch cable can be also classified by the types of fiber optic connector. For example, LC fiber optic patch cable is named as it is with LC connector. Similarly, there are SC, ST, FC, MT-RJ, E2000, MU and MPO/MTP fiber optic patch cables. What’s more, there are PC, UPC, APC type fiber patch cords, which are differentiated from the polish of fiber connectors.

Which Patch Cable Should I Choose for My Fiber Optic Transceivers?
Now, I will take the Cisco fiber optic transceiver as an example to discuss this topic. For example, we need to choose a right patch cable to connect Cisco fiber optic transceiver SFP-10G-SR and X2-10GB-SR. Which patch cable to use? According to “Cisco 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix”, we may know that SFP-10G-SR is the 10GBASE-SR SFP+ transceiver module for MMF, 850-nm wavelength, LC duplex connector. And X2-10GB-SR is the 10GBASE-SR X2 transceiver module for MMF, 850-nm wavelength, SC duplex connector. Obviously, this two knids of optica trancseivers are both for MMF, so we should choose a multimode patch cable. Besides, we know X2-10GB-SR is designed for SC duplex connector and the SFP-10G-SR is designed for duplex LC connector, so we should use a patch cable with SC-LC duplex connector.

The Most Common Used Pacth Cable Selection
In the way mentioned above, you could choose right fiber patch cable for your other transceiver modules. Keep in mind that if your transceiver modules are not Cisco’s, you need to ask your brand supplier to get the corresponding compatibility matrix. In fact, in terms of a same kind of optical transceiver, different supplier may provide the transceiver with different specifications. Here I may list the most common used patch cables selection. Hope to give you smoe reference.

10G fiber optic transceivers are designed for 10G or 10Gbit/s data transmission applications including 10 Gigabit Ethernet, 10 Gbit/s Fiber Channel, Synchronous optical networking. After years of 10 Gigabit Ethernet’s existence, there has been various different form factors and optics types introduced.

Nowadays, 10G transceivers series mainly includes 10G XENPAK, 10G X2, 10G XFP and 10G SFP . XENPAK was the very first MSA for 10GE coupled with been the biggest form factor. X2 was later competing standards with smaller form factors. XFP came after X2 and it is also smaller. SFP offer a smaller form factor and also the ability to offer 1G/10G combo ports on hardware. This is a guide to these module types and optical standards currently available.

X2 defines a smaller form-factor 10 Gb/s pluggable fiber optic transceiver optimized for 802.3ae Ethernet,ANSI/ITUT OC192/STM- 64 SONET/SDH interfaces,ITUT G.709,OIF OC192 VSR,INCITS/ANSI 10GFC (10 Gigabit Fibre Channel) and other 10 Gigabit applications.X2 is initially centered on optical links to 10 kilometers and is ideally suited for Ethernet,Fibre Channel and telecom switches and standard PCI (peripheral component interconnect) based server and storage connections. X2 is physically smaller than XENPAK but maintains the mature electrical I/O specification based on the XENPAK MSA and continues to provide robust thermal performance and electromagnetic shielding. The 10GB X2 fiber optic transceivers series include X2-10GB-SR, X2-10GB-LR, X2-10GB-ER and X2-10GB-ZR, they are designed based on the X2 MSA and IEEE802.3ae. They’re created for the integrated systems solution provide, fiber optics distributor along with other IT distributors.

FiberStore SFP (Small Form-factor Pluggables) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. SFP module (volume ratio GBIC module reduced by half, and more than double the number of ports can be configured in the same panel. SFP module GBIC function basically the same, some switch vendors called the small of GBIC (Mini GBIC).

SFP transceivers have many different kinds of sending and receiving, users can choose appropriate for each link of the transceiver, and to provide a based on the available optical fiber type (such as multimode optical fiber and single mode optical fiber) can achieve “optical performance”. Available optical SFP modules are generally divided into the following categories: wavelength 850 nm / 550 m distance of the MMF (SX), 1310 nm wavelength / 10 kilometers distance from SMF (LX), 1550 nm wavelength/XD 40 kilometers distance 80 km, 80 km distance from ZX, distance of the EX or EZX, and DWDM. SFP transceivers provide copper interface, also makes the main host devices can also be designed for optical fiber communication via UTP cable communication network. There is also a wavelength division multiplexing (CWDM), and single fiber “two-way” (1310/1490 nm wavelength ascending/descending) of the SFP.SFP Transceivers also have many brands,Such as major brands we provide Cisco SFP(cisco mini gbic),HP SFP, Juniper SFP, Netgear SFP etc..All our fiber transceivers are 100% compatible with major brands.
